基于BPPM调制的非直视紫外光通信在异步周期脉冲干扰下的性能分析
Performance analysis of BPPM-based NLOS UVC system under asynchronous periodic pulse jamming
摘要
Abstract
As the application of ultraviolet communication(UVC)technology on unmanned aerial vehicle platforms expands,ground-based non-line-of-sight(NLOS)UVC systems face potential jamming threats.Focusing on NLOS UVC systems that employ binary pulse-position modulation(BPPM),this paper derives the joint probability mass function of jamming signals of two slots in a BPPM symbol under asynchronous periodic pulse jamming.Then,theoretical closed-form expressions for the average bit error rate and achievable data rate are obtained and validated through Monte Carlo simulations.Finally,system performance is evaluated under varying jamming distances,transmitter peak optical powers,and parameters of jamming pulses.The results show that,compared with on-off keying,BPPM offers significantly improved anti-jamming performance in NLOS UVC systems.关键词
